Application filed December 16, 1911. Serial No. 666,308,

I 5 New Cross, London,S. E., England, have invented new and usefulImprovements in and Relating to Mechanism'for Producing Gas-- LightedFlash-Signs and'the Like for Advertising Purposes, ofwhich the followingThis invention relates to improvements in mechanism for producin gaslighted flash signs and the like for a vertising purposes and has forits object theprovision of means where'b the motive power of the gas isnot only utilized to work the mechanism for pro ducing an intermittentsupply of gas as an illuminating agent but is in addition caused a f toprovide the motive'powerby which the ..20 lighted flash sign is moved.

I My invention therefore conslsts in the combination of a .gas drivenintermittent control apparatus with 'a revolving lantern or supportcarrying advertising matter and means by which the intermittent motionis transmitted from the gas control mechanism to the lantern or supportcarrying the ad vertisement.

' One way of carrying the invention into "'30 eifect is by utilizing thelantern control y mechanism operated the gas used in the burner such asis described in. the specification of B. an. Letters Patent No. 1009313"and eonnectingfto,any'reciprocating" art of sasaidf apparatus a.connecting mec amsm I which 13; adapted to give an intermittent .ro-

tation-ftof the lantern or support carrying the advertisements.

.rder that theinvention may be the iobetterunderstood I now proceedtodescribe the samein relation to the accompanying drawin reference beinghad to I the letters and gates marked thereon.

Like letters refer to like parts in the vari- 'ous figures, in whicht-Figure 1 is a view of tus with my invention applied thereto. Fig. 2 is aplan of the ratchet wheel, the operatinglever andpa-wl-and theretainingpawl.

The flash li ht device a is similar to that described in t especification of U: S. A. Letters Patent No. 1009313 and is given only.as an example of a motor mechanism. The

lantern bis pivotally mounted preferhbly on an anti-friction bearing 0upon the gas standard d. The lower part of the lantern fixedly carries aratchet wheel 6 with which engages aretaining pawl f mounted on thestandard d to prevent backward motion and an operating spring pawl gmounted on the end of the bell crank h. The lever i of the mechanism ais connected to the bell crank h by a connecting rod 1' and a series ofholes k a are provided in both bell crank and lever to vary the leverageand the consequent motion therefrom. As the mechanism a is operated bythe gas the lantern is revolved thereby by v I Specification of LettersPatent. Patented Sept. 16, 1913. v

a step by step motion and the r volution will continue so long as thegas, is being used.

Having thus fully described my invention, I claim as new and desire tosecure by Let tersPatenttv A mechanically operated. gas flash lightdevice consisting of in combination, a motive mechanism adapted to beintermittently actuated by the gas pressure of supply, a lighting-burnersupplied'by gas from the intermittent exhaust of the said motivemechanism, a revoluble lantern adapted to carry-advertising matter orthe like and connecting means for transmitting the intermittent motionof the said motive mechanism to the said Iantern,'substantial1y asdescribed.

I In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
